Mantle of the Mammoth

Wondrous item, rare (requires attunement)

This thick, warm cloak is covered in insulating fur. A pair of tusks adorn the edges of the hood. While wearing it, you have resistance to cold damage, and your melee weapon attacks against prone creatures score a critical hit on a roll of 19 or 20. In addition, you count as one size larger for the purposes of being grappled, shoved, or otherwise moved against your will, and if a creature within 5 feet of you attempts to physically knock you prone, that creature is instead knocked prone if you succeed on the check or saving throw against it by 5 or more.

Those who were wise to the ways of the Everglacier were often wise to wear the furs of the giants that roamed the bitter land.
